An accurate timeline will be constructed once we determine how long it will take for the ordered parts to arrive. A tentative schedule is as follows:
DEVICE PARTS |
|
- Purchase suitable mouse
The original mouse purchased (VAL Gear Optical Scroll Mouse) was purchased and tested. We found that it draws too much current for Mac OS X systems, and it was only compatible by Mac OS 9 and Windows operating systems. A Logitech Optical Mouse was designed and tested to be OK.
